## Purpose: This script generates Figure 1.
## Inputs:  /scratch/jhb362/zilinsky_2023/data/results/VIMP_ranger/VIMP_2024.*-months.*FALSE_temp-chg12.RData
##            - Variable importance results generated by NFR_vimp_prep.R
##            - Summarized on the NYU HPC into PSRM_simple_months_chg12.RData via NFR_data_prep.R
## Outputs: ./figures/fig1.pdf
